TPS3840DL45DBVR from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | RESET | tri_state | Open-drain, low-active reset output; pulled low when VDD drops below VIT- (4.5V) or MR is driven below VMR_L (0.6V max), released to high-impedance when VDD rises above VIT+ and MR is floating or above VMR_H (0.7×VDD min) after reset delay time tD; external pull-up resistor required. |
| 2 | VDD | power_in | Input supply voltage monitored by internal comparator; operating range 1.5V to 10V with fixed negative threshold VIT- = 4.5V and hysteresis VHYS = 200mV for this variant. |
| 3 | GND | power_in | Ground reference and return path for supply current. |
| 4 | MR | input | Manual reset input; pulling to VMR_L (0.6V) asserts reset output, pulling above VMR_H (0.7×VDD) or leaving floating releases reset after programmable delay tD, with internal 100kΩ pull-up resistor. |
| 5 | CT | passive | Capacitor timing pin for user-programmable reset delay; connect external capacitor (≤10µF) to ground to adjust delay from 50µs (open) to maximum 6.2s (10µF), or leave floating for minimum 50µs fixed delay. |
